| (54) | MICROWAVE TREATMENT DEVICE |
| (57) A microwave treatment device according to one aspect of the present disclosure includes
a heating chamber, a microwave generator, an amplifier, a feeder, a detector, a controller,
and a storage. The microwave generator generates a microwave having an arbitrary frequency
in a predetermined frequency band. The amplifier amplifies the microwave and outputs
the amplified microwave as incident microwave power. The feeder supplies the incident
microwave power to the heating chamber. The detector detects the incident microwave
power and reflected microwave power that returns from the heating chamber to the feeder.
The storage stores the incident microwave power and the reflected microwave power
in association with the frequency of the microwave and time elapsed since the start
of heating. The controller causes the microwave generator to execute a frequency sweep
over the predetermined frequency band. The controller controls the microwave generator
and the amplifier on the basis of the incident microwave power and the reflected microwave
power detected during the frequency sweep. According to the present aspect, the heating
evenness can be improved.
